The Boy in the Stopped Pyjamas. It’s basically Holocaust fan fiction. The whole book just kinda treats the concentration camps with a levity that just feels disrespectful. Also the main character is dumbest 9year old ever to exist. I actually know people who read this book as a class in school. I don’t know why with the plethora of literature about the Holocaust, many of it written by actual survivors, that only school would choose The Boy in the Stripped Pyjamas to read as a class
That is entirely dependent on the type of book. Some books you can breeze through others are a bit more dense.
You say you are somewhat new to regular reading for pleasure and if that’s the case I don’t think 20 pages sounds all that bad. It’s just one of those things where the more you do it the better/faster you get at it. Are you rereading cause you loose your place or because you aren’t fulling absorbing it first time. If the later is the case then try slowing up a bit first. Like I said before the more you read the faster you’ll be able to do it and absorb it over time.
And don’t sweat how fast you read. Reading isnt a competition, as long as you’re enjoying yourself it’s fine.
